How about this. When I turned my headlights while driving down the road today, the truck jumped, like I turned it off, turned the key on, and dumped the clutch to start it. Then when I cracked the rear window, it did the same thing. I'll have the alt. checked tomorrow as well. I am putting a transmission in Sat. so it might have to wait till Mon. Thanks again for you input. robert


I had a similar problem on both my 4Runners at different times. On one when I turned on lights or other electrical load it died/jumped less than a second like it died. I cleaned and retightened the battery ground terminal and it never has happened again. I removed the little plastic spacer in the ground lug so it could go tighter onto the battery terminal.

The other 4Runner would do the same thing whenever I hit a bump in the road. This was really annoying and unnerving. Turned out the EFI relay was loose in its plug and would bounce when I hit a bump causeing the EFI system to shutdown for a second. Then it would come back on when the relay reseated. I pushed the EFI relay in tight and problem solved for good.

good luck
